Identification of Scavenger Receptor Class B Type I in the Hepatocytes of Hypercholesterolemic Rats

open access: yesMicroscopy and Microanalysis, 2001
Abstract The levels of plasma high density lipoproteins (HDL) are inversely related to the incidence of atherosclerosis and coronary heart disease. This protective effect of HDL is thought to be involved in the reverse transport of cholesterol from peripheral tissue to the liver. The scavenger receptor class B type 1 (SR-BI) is the first

Bacteria‐Derived Extracellular Vesicle as A “Trojan Horse” for Selective M1 Macrophage‐Targeting in A Multi‐Cellular Entanglement Environment

open access: yesAdvanced Functional Materials, EarlyView.
The temporary transition of macrophages from a pro‐inflammatory phenotype of macrophages (M1) to an anti‐inflammatory phenotype of macrophages (M2) is crucial for tissue repair and regeneration processes. Bacterial outer membrane vesicles (OMVs) are utilized as a “trojan horse” for specific M1 macrophage‐targeting and anti‐inflammatory drug delivery ...

Biomimetic Co‐delivery of Lenvatinib and FePt Nanoparticles for Enhanced Ferroptosis/Apoptosis Treatment of Hepatocellular Carcinoma

open access: yesAdvanced Healthcare Materials, EarlyView.
This study introduces a novel HCC treatment using poly lactic‐co‐glycolic acid (PLGA) nanoparticles encased in HCC cell membranes to co‐deliver Lenvatinib and FePt nanoparticles. This approach improves treatment efficacy by enhancing ferroptosis and apoptosis.

A lipidated peptide derived from the C-terminal tail of the vasopressin 2 receptor shows promise as a new $β$-arrestin inhibitor [PDF]

open access: yesPharmacological Research, 2025, 107597
$\beta$-arrestins play pivotal roles in seven transmembrane receptor (7TMR) signalling and trafficking. To study their functional role in the regulation of specific receptor systems, current research relies mainly on genetic tools, as few pharmacological options are available.

The effect of Ta oxygen scavenger layer on HfO$_2$-based resistive switching behavior: thermodynamic stability, electronic structure, and low-bias transport [PDF]

open access: yes, 2016
Reversible resistive switching between high-resistance and low-resistance states in metal-oxide-metal heterostructures makes them very interesting for applications in random access memories. While recent experimental work has shown that inserting a metallic "oxygen scavenger layer" between the positive electrode and oxide improves device performance ...

Radiation‐Resistant Bacteria Deinococcus radiodurans‐Derived Extracellular Vesicles as Potential Radioprotectors

open access: yesAdvanced Healthcare Materials, EarlyView.
Deinococcus radiodurans‐derived extracellular vesicles (R1‐EVs) provide radioprotection against total‐body irradiation‐induced acute radiation syndrome in mice. R1‐EVs mitigate oxidative damage by scavenging free radicals, promoting intestinal repair, enhancing hematopoietic function, and modulating immune responses. This study highlights the potential

Hole Scavenging and Photo-Stimulated Recombination of Electron-Hole Pairs in Aqueous TiO2 Nanoparticles [PDF]

open access: yesarXiv, 2004
It is shown that 532 nm and 1064 nm laser photoexcitation of trapped electrons generated by 355 nm photolysis of aqueous titania (TiO2) nanoparticles causes rapid photobleaching of their absorbance band in the visible and near IR. This photobleaching occurs within the duration of the laser pulse (3 ns FWHM); it is caused by photoinduced electron ...

Hollow‐Structured Nanorobot with Excellent Magnetic Propulsion for Catalytic Pollutant Degradation, Anti‐Bacterial and Biofilm Removal

open access: yesAdvanced Healthcare Materials, EarlyView.
A hollow‐structured Fe3O4@AgAu@PDA‐ZnPc nanosphere has been developed, exhibiting controllable catalytic activity and “photothermal‐photodynamic‐Ag+” coupling antibacterial characteristics. When subjected to a rotating magnetic field, these performances are uniquely enhanced by magnetic propulsion, allowing the nanosphere to function as a magnetic ...
